HEADLIGHT.

Specification of Letters Patent.

Patented April 30, 1907.

Application liled January 30, 1906. Serial No. 298,649.

To will whom it may concern,.-

Be it known that I, MANEs E. FULD, a citizen of the United States, residing at Baltimore city, State of Maryland, have invented certain new and useful Improvements in Headlights; and I do hereby declare the iollowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in head lights for use more especially by physicians and surgeons in which the light is carried on the head of the wearer and the rays are obscured from the eye of the wearer, but are thrown on the object under examination, such for instance as the larynx of a patient.

My invention will be understood by reference to the accompanying drawings in which the same parts are indicated b y the sameletters throughout the several views.

Figure l is a perspective view showing the apparatus mounted on the head of the wearer. Fig. 2 shows ona larger scale the iront end oi the spring clip lor engaging the head of the wearer with the parts mounted thereon. Fig. 3 shows a rear end of the spring clip and illustrates the means of making the electrical connections with the battery (not shown). Fig. 4 shows a section along the line 4-4 of Fig. 2. Fig. 5 shows a central vertical section through the apparatus and includes the electric light and the various parts in proximity thereto, parts being shown in elevation. Fig. 6 is a section along the line 6-6 of Fig. 5 and looking'in the direction of the arrows. Fig. 7 shows a section through the lamp socket and adjacent parts, the section being at right angles to'that shown in Fig. 5, and Fig. 8 shows the insulating plate to which the terminals of the leading in wires are connected, the lining plate which goes next the forehead of the wearer having been removed. This iigure shows the opposite side of the in'- sulating plate from that shown in Figs. 1 and 2 and on a larger scale than in either of those ligures.

A represents a spring clip adapted to fit the head of the wearer and provided with an enlarged plate A to fit the-back oi the head, and a shield or plate to iit the forehead. This shield is preferably made of insulating material in' two pieces, the Jfront piece B being attached to the clip A, and the rear piece B being attached to the front piece by the screws b2 passing through holes b".

The leading in wires are preferably inclosed in a cable C which passes along the top of the clip A and is biurcated at each end, as shown in Figs. 2 and 3. At the rear end the leading in wires pass through an insulatin block C fastto the clip A, and are connecte to contacts c3 which are adapted to engage in contact sockets c in the insulating block C2, see Fig. 3, through which block the leading in wires from the cable C3 are led. The wires of this cable C3 connect with the poles oi the battery, not shown. The battery may be carried in the pocket of the user, or may be placed in any convecient osition and the wires connected thereto ead up along the back oi the operator and are out of the way.

At the front end of the cable C the wires c, c are bifurcatedias shown in Fig. 2, and are connected to the binding posts b, b', scc Figs.

i 2 and 8, and these posts are connected by the conductors D, D let into the face or' the block B to the binding posts d, d', and from these binding posts d, d the circuit is completed through the lamp, as will be hereinafter described. l

E represents an inner telescopic tube and E an outer tube sliding thereon carrying the lens E2, by means of which the light from the lamp may be focused on any desired spot.

F represents a lamp socket which is mounted in the insulating block F which block is detachably held in means of the spring clip F0 having a lug fX enga ingin a notch in the tube E. The base M o the lamp Mis screwed into this socket as at f 0. N represents a reflector that is held in place by the latter is screwed 1n place. v

Theblock F is recessed to receive the metallic disks F3 and F5, and the metallic spring F4. The disk F3 is provided with a contact point f3 which carries the current into the lamp M.

Contact is made between the disk F5 and the plug G by means of the spring F4. This plug G 1s provided with a tongue'g pivoted at vg in the fork h of the 1pin H, whlch is held in lace in the brackets i', K2, by means of the This piu H is insulated as at ook nuts H.

the inner'tube E by IOO I, I', I3 so that the current may pass -from the binding postv 'n' and conductor D to the bracket K and through the pin H 'and tongue G to the lamp M.

l The lamp `socket F is secured to-the insu-V ceive the screws L which en age the arms le' of the tube K.which is ma e integral with the bracket K, see Figs. 2, 4 and 5.l The current from the lamp therefore passes through the lamp socket and thence through pins f, through the screws L and the arms 7c,

tube, K and the bracket K to the binding post d, land through the conductor D .and binding post b to the Wire c, see Figs. 2 and8. Thus it will be seen that the circuit Jfrom the cable C is completed through the lamp. The screws L should be setup tight enough to create the requisite friction so that the telesco ic tube carrying the lamp may be held inc ined at the desired angle and yet may be readily swu up or down, when desired.

Thus it wil be seen that I provide a simple and eiective head 1il ht that may be readily applied and remove and which will not interfere in any way with the movements of the wearer. f c l It will be obvious that various modications might be made in the herein described apparatus which could be used Without departing from the spirit of my invention.

-in wires to a source of ectriclamp adof said support for connecting said leading Y electricity, substantially as described.

2.- The combination with a spring clip provided with front and rear end plates adapted to engage the head of the wearer, of a bracket secured to the front end plate, an electric lamp socket lhinged to said bracket,

and leading in wires mounted onsaid clip and electrlcally connected to said lamp socket, an inner .tube inclosing said lamp socket, a lamp mounted in said socket, an annular reflector mounted on t'he base of said lamp and inclosed in said tube, and an outer telescopic tube carrying a lens mounted exterior of said inner tube, substantially as described.

y In testimony whereof, I vaiix my signature, in presence of two witnesses.
